GAR-BOLSTER.

Specification of Letters Patent.

Patented May 7, 1918.

Application filed January 12, 1918. Serial No. 211,549.

To all whom z't may concern:

Be it known that I, ELLIS W. Tns'r, a citi zen of the United States, andresident of Michigan City, county of Laporte, and State of Indiana, haveinvented certain new and useful Improvements in Car-Bolsters, of whichthe following is a specication, and which are illustrated in theaccompanying drawings, forming a part thereof.

The invention relates to improvements in holsters for railroad cars.Bolsters are preferably formed relatively deep adjacent their center andtapering toward the ends to provide suiiicient clearance for otherparts, as well as eliminate unnecessary weight and material.

One of the objects of this invention is to provide means for readilyconstructing such a bolster from channel members and plates of uniformcross-section, and at the same time provide adequate support for theside body bearings connected to the under side of the bolster.

One embodiment of the invention is illustrated in the accompanyingdrawings, in which- Figure 1 is a side elevation, one half in section,of a bolster embodying the features of this invention;

Fig. 2 is a plan view of the bolster, a portion being broken away;

Fig. 3 is a section on the line 3-3 of Fig. 1; and

Fig. 4 is a perspective view of one of the parts of the bolster.

The bolster shown in the drawings comprises two channels 10, each havinga central web 11 and upper and lower flanges 12 and 13. The flanges ofeach pair of channels are arranged in opposite directions, and areriveted to upper and lower plates lll, 15.

Since the channels 10 are of uniform cross-section and preferably thebolster should taper adjacent its ends, the end portions of the lowerflanges 13 and part of the central web 11 of each channel is cut awayand replaced by an angle piece 16. One flange 17 of the angle piece isconnected to the central web 11 of the channel, while the other flange18 projects laterally and is inclined upwardly toward the end of thebolster. The flange 18 is riveted to the lower plate 15.

To the under side of the late 15 and angle piece 16 is attached a si ebody bear- ,and bottom plates 14 and 15 ing block 19, and to strengthenthe bolster at that point ribs 20 are provided between the ianges 17 and1S immediately above the side bearing block.

As the flange 17 of the angle piece is riveted to the inner face of theweb 11, it is necessary to cut away much more of the web than isrequired to produce the tapered end to the bolster in order to give roomfor the ribs 20. Consequently the piece cutaway from each end of eachchannel is substantially rectangular to provide ample room for the ribs20. The corner 21 of this cut away portion 22 is preferably rounded toavoid the development of cracks.

Each flange 17 is formed with an offset portion 23 of the sameconfiguration as the cut away part 22, so that the edge of the latter isin substantial engagement with the outer edge of the oset portion, andthe offset portion 23 is in substantially the same plane as the web 11.

rlhe angle pieces are formed with end plates or flanges 24, adapted toclose the end of the central passage through the bolster as well asextend between the projecting flanges of the angle piece and channel.The top are centrally apertured to receive the king bolt, and a -socketblock 25 for this bolt is arranged within the bolster.

I claim as my invention- 1. A body bolster of box form having lateraloutwardly directed flanges adjacent its top and bottom, the lower partof the side members of the bolster being cut away adj acent each end,angle members having one flange attached to the sides of the bolsteradjacent said cut away portions, said flange decreasing in width towardthe ends of the bolster, the other flange of said angle members beinginclined upwardly toward the end of the bolster, and reinforcing ribsbetween the flanges of said angle members, the edge of said cut-awayportions being spaced apart from said last-mentioned flange adjacent thereinforcing ribs to allow said ribs to extend under said edges.

2. A body bolster of box form having lateral outwardly directed flangesadjacent its top and bottom the lower part of the side members of thebolster being cut away adjacent each end, angle members having oneflange attached to the inner face of the side wallos of the bolsteradjacent said cut away portions, the other ange of said angle membersbeing inclined upwardly toward the end of vvthe bolster, a body sidebearing block secured to the under side 'of Asaid angle members, andreinforcing ribs between the anges of said angle members above rsaid'bearing. l

3. A body bolster 'of box form having lateral outwardly directed flangesadjaoentits top and bottom, the lower part of the side members of thebolster being out away adjacent each end, angle members having oneCopies of this patent may be obtained for ve cents each. by addressingthe Washington, D. C.

flange attached to the sides of the bolster adjacent said out awayportions, the other flange of said angle Jinembers being inclinedupwardly towafdthe end of the bolster, said lfirst-mentioned flange ofthe angle member lbeing offset between the edge of said out away portionand said second flange of the angle member whereby said offset portionforms a substantial continuation of the side of the bolster.
